2n404a fuzz with LOTS OF KNOBS?!!?

[inverseroom]

Hey all--haven't been around lately because I've been DIY-synth obsessed.  But now I have a yearning for a massive, knob-littered, feedbacking, oscillating fuzz.  I may even rackmount it.

I happen to have a couple of matched 2n404a's that Steve sold me, and which I never got around to using...are there any good ultra-tweakable circuits that like these transistors?

Thanks!
